SPECIFICATION forming partof Letters Patent No. 536,586, dated March 26,1895.

' Application filed December 5, 1894. Serial No. 530,931. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM B. SMITH, a citizen of the United States,residing at Covington, in the county of Kenton and State of Kentucky,have invented certain new and useful Improvements in Railway-Tracks andI do hereby declare the following to bea full, clear, and exactdescription of the invention, reference being had to the annexeddrawings,

IO which form part of this specification.

In Letters Patent No. 528,309, granted Oc-' tober 30, 1894, to myself,John W. Fisher and Thomas Clifton, certain devices are shown forcoupling a vertically-yielding track to a me- I5 tallic cross-tie; butin the present case these devices are somewhat modified, and otherattachments are so combined therewith as to afford a very rigid orimmovable track, which is entirely free from fish-plates, spikes, 850.,the

details of this new construction being hereinafter more fully described,and then pointed out in the claims.

In the annexed drawings, Figure 1 is a plan of a portion of my rigidrailwaytrack, the

center of a tie being broken away, and the fasteners for one of therails being omitted. Fig. 2 is end elevation of said track. Fig. 3 is anenlarged transverse section of a rail and its fasteners. Fig. 4 is anenlarged transverse section of one of the metallic-ties, said sectionbeing taken at the line Z-Z, of the preceding illustration, and the railbeing seen in elevation. Fig. 5 is a sectional plan of the under side ofa fastening cramp, which is seen in the act of being attached to a tie,the lower plate of said cramp being broken away to expose a pair oflugs.

The metallic cross-tie that supports my rigid track is substantially thesame as seen in the patent above referred to, being composed of abase-plate A, vertical side-flanges B, B, outer abutments O, O, D, D,and inner lugs E, E, F, F, the lugs being perforated, as seen at e, inFig. 2 to admit a square bolt'G, that carries a non-rotatable crampconsisting of an upper plate H and a lower plate H, these two members,H, H, being shaped like jaws that can grasp the base of a rail and achair I that assists in supporting said rail K. This cramp H, H, fitssnugly between the flanges B, B, of the tie; but the lower plate H, iscut away, as seen at h, h, in Figs. 4: and 5, to clear the end flangesl, I, of the chair, which flanges rest upon the base-plate A.

h, in Figs. 3 and 5, represents lugs or ribs projecting from the underside of plate H, for the purpose of engaging with notches k in the railbase, which base fits between the upturned lips 2,1", of the chair. Theinner lip of each chair must be cut away, as seen ate, in Figs. 1 and 3,to allow the lugs h, to enter the notches k, but by cutting away eachlip, as above described, there will be no necessity for inserting thechair within the tie in any special manner.

The square-bolt G, which is usually secured in place by a spring-pin g,seen in 'Figsll and 4, has a keeper J applied to it, said keeper beingof the bell-crank shape represented in Fig. 2, and adapted to engagewith a notch 70, in the rail-base. The vertical arm of this keeper iscarried down a suitable distance, outside the tie flange, and terminateswith a short, lateral bend j that engages with a slot bin said -flange,by which arrangement shifting of said keeper is effectually guardedagainst. For ties of ordinary width, one'of these keepers will besufiicient for each rail, but for wider ties, to support the abuttingends of a pair of rails, I prefer employing two of these bellcrankdevices, as represented in Fig. 1.

In laying my improved railway-track, the various chairs I are firstproperly placed in the trough-shaped ties, and then the rails K areseated in therecesses L, between the abutments 0, and lugs E. The crampH H, is now inserted between the flanges B, B, the keepers J applied tothe exteriors of said flanges, and then the bolt G is passed throughsaid cramp and keeper and secured in place by the pin g, or otherwise.Consequently, the rails are rigidly secured to the ties, the stoutabutments G, O, D, D, preventing outward shifting of said rails, Whilethe cramps H H, secure them against upward and inward movement,and thekeepers J, by engaging with the base-notches it, hold said rails againstlongitudinal play. This longitudinal shifting of e aefss the railsisfurther guarded against by cansing the lugs or ribs h", of the crampto engage with the notches 7c, of the rail-bases.

It is preferred to have the longitudinal bore h, of the cramp slightlyout of line with the holes e, of the tie-flanges B, B, as seen in Fig.5, in order that the act of driving a tapering key G, through said borewill wedge said cramp toward the rail a limited distance, after whichact, the bolt proper, G, is forced in until it gradually displaces saidwedge, and thus completes the operation of securing the rail in place;but previous to this application of the cramp filling pieces, orwashers, may be inserted between it and the rail to compensate for anypossible wear and tear of the track.

It will be noticed that the present construction of track, like thatseen in my patent previously referred to, dispenses entirely withfish-plates and their objectionable bolts and nuts, and as thecross-ties are Wholly metal lie, the use of spikes is impossible.

Finally, ina modification of my invention, the chairs may be omitted, inwhich case the cramps will simply grasp the rail bases.

1 claim as my invention 1. The combination, in a railway-track, of ametallic cross-tie, having upturned sideflanges; a chair fitted Withinsaid tie; a rail supported upon said chair; a non -circular bolt securedin said side-flanges; and a non-rotatable cramp carried by said bolt,and grasping the chair and rail-base, thereby dispensing withfish-plates, bolts and spikes, in the manner described.

'2. A railway-track consisting of rails rigidly secured to metalliccrossties by a system of non-rotatable cramps fastened between verticalflanges of said ties, and bell-crank keepers attached to the exteriorsof said flanges, as herein described.

3. A railway-track consisting of rails rigidly secured to metalliccross-ties by a system of non-rotatable cramps fitted between verticalflanges of said ties, and keepers attached to said flanges and engagingwith notches in the rail-bases, as herein described.

4. A rigid railway-track consisting of the metallic cross-ties A, havingabutments G, O, D, D, lugs E, E, F, F, and perforated sideflanges B, B,e, and rails K, K, resting upon said flanges, in combination with asystem of non-rotatable cramps H H, that grasp the rail-bases, all asherein described.

5. The combination, in a railway-track, of the metallic cross-tie A,havingupturned sideflanges B, B; a rail K, supported upon said flanges,and having its base notched at 70; a-

non-circular bolt G, secured to said flanges; and a non-rotatable crampH H, carried by said bolt, and provided with a lug h", that engages withsaid notch 7c, all as herein described, and for the purpose stated.

6. A rigid railwaywrack, consisting of the metallic cr0ss-tie A, havingupturned sideflanges B, B; a chair I, having upturned lips t', '11, anddownturned end-flanges I,I, rest upon the base-plate of said tie; a railK carried by said chair; and a non-rotatable cramp H H, fitted betweenthe tie-flanges B, B, and grasping said chair and the base of said rail,all as herein described, and for the purpose stated.

In testimony whereof I affix my signature in presence of two Witnesses.

WILLIAM B. SMITH.
